Over the years, the cash slice of the PP has grown on me the most.
One of the reasons I love the PP is that it provides an integrated framework for merging "emergency funds" (i.e.
x months/years of living expenses) into the portfolio management process: it gives cash a job; invites it to be a member of the pack; installs it as a vital cog in the machine. This is a practical advantage of cash that Sophie has frequently emphasized as really liking, as well.
I always laugh when someone states they are "100% stocks", yet the have 1-2 years of living expenses in cash... so,
they aren't actually 100% stocks, then. This puts the PP at a disadvantage when it is backtested against other asset allocation strategies that exclude cash savings. I like to water-down portfolios with cash when comparing them to the PP for this reason. Alternatively, you can compare them to the 33x3 PP, but I dislike this approach because it doesn't model the PP's trademark stability. What you will find is that returns of most asset allocations, even the stock heavy ones, aren't nearly as impressive when you factor for the cash drag that the PP automatically accounts for.
Cash is oxygen. Incomes can be disrupted and disappear. My spouse and I both lost our jobs
in the same month back in 2021. Words cannot describe the peace of mind provided by the 25% cash slug in the PP to depend upon, regardless of market conditions. I knew that, no matter what happens in the markets, that I could draw down on that cash for months before triggering a re-balancing band or selling assets at a loss if the PP is having a bad year (2022, anyone?).
William Bernstein described the importance of cash very aptly in
Deep Risk:
Shallow risk mandates deep liquidity. If you do not have a large amount of highly liquid and safe reserves -- for the average individual, Treasuries and CDs -- you will not have the wherewithal to weather the employment setbacks that comes with turbulent markets, to purchase stocks at low prices, and to keep your courage up when you need it most.
...generous portfolio liquidity is the sine qua non of any successful strategy for investing, or for that matter, for life in general
Ironically,
Deep Risk is largely a criticism of the PP, and Bill doesn't include cash in any of his suggested asset allocation schemes. I find this a little puzzling, given his clear recognition of the indispensable nature of cash. To me, Harry Browne's inclusion of cash as an integral component of the PP was genius, not arbitrary or misguided.
frugal, how reliable are those income streams that you mentioned? Are they guaranteed? My experience is there are no guarantees in life. Cash provides an indispensable buffer in case your "reliable" cash flow streams are disrupted.
If you don't like the cash drag imposed on the portfolio, here is one potential solution:
decide the size of a cash emergency fund you want/require and multiple that number by 4. Maintain the PP at that level and dedicate the rest of your assets to whatever growth oriented strategy you prefer with the rest of your liquid assets. This way you always have a cash buffer to fall back on, and because it is contained in the structure of the PP you don't have to worry about the many vulnerabilities/risks that cash is exposed to. Kind of brilliant, actually! That's why I love the PP and have stuck to it since 2014.
